Description

If a normal electronic focuser without clutch function is installed on a Celestron SCT, we can no longer use its original knob to focus. However when using SCT we often need to focus quickly or manually by tuning the knob. But if we don't use electronic focusers, then we may hard to achieve good focusing accuracy.

To resolve this issue we developed dedicated adapters for Celestron C8/925/11/14 and their HD version. With those adapters Oasis Focuser can be installed on Celestron SCT. Oasis Focuser is a clutch electronic focuser, and the adapter has a special-designed knob. In this way SCT users can do focus with an electronic focuser or with the knob. They can switch between the electronic focuser and the knob freely. This is a perfect focusing system for SCT.

This product has two models, CSA8925 and CSA1114, of which CSA8925 can be used for C8/C925, and CSA1114 can be used for C11/ C14. The appearance of the product is shown in the figure below.

Oasis Focuser main body can be easily installed or uninstalled with a clamp. The main body can be shared between different telescopes in a easy way, which saves money for you. The appearance of the adapter is also beautiful. Even when the main body is removed, the knob can still be used, and the appearance of the adapter is still very beautiful.

As shown in the following picture, the diameter of the focusing shaft of C11/C14 has two size, ie., 21.8mm and 22mm. We made two different knobs for them accordingly. So CSA1114 has two sub-types, one is CSA1114A, and the other is CSA1114B. CSA1114A is for 21.8mm shaft, and CSA1114B is for 22mm shaft.

Below is an example of installation on C14HD.
